LOCKING DEVICE Filed Sept. 12. 1931 2 Sheets-Sheet 2 Patented ug. 2, 1932 RICHARD J'. GOLLONG AND RALPH .EL CARTER, 0F JOHNSON CITY, TENNESSEE, AS- SIGNORS TO AMERICAN GLANZSTOFF CORPORATION, OF NEW YORK, N. Y., A COR- PORATION OF DELAWARE Application led September 12, 1931.

rlhis invention relates to the treatment of threads in a washing or treating apparatus, and more particularly to an improved locking means for preventing any accidental 45y movement of the feed and discharge pipes while the system is in operation. In describing the invention reference will be made'to the use of the locking means in connection with an apparatus for treating artificial filaments, but it is not intended to limit the locking means to its use in the specific apparatus described.

In the treatment of -artificial silk such asv is disclosed in a co-pending application Se- 15 rial Number 539,730, filed May 26, 1931, in

the names of Oppenlaender, Gollong and Carter, filaments may be wound on perforated receivers which may be placed in tiers of three or more in a tank. Treating liquid 2 is then allowed to flow into the tank and after the treating operation is emptied from the tank by vacuumor other suitable means. It is an object of this invention to provide an improved locking means for preventing -2 any accidental movement of the feeding and discharge pipes during the treating operation.

More particularly it is an object of this invention to provide a connection -between the treating tank and the various feeding and discharge, pipes which will prevent any movement of the connection until the treating tank is emptied.

In describing the invention reference will be made to the accompanying drawings in which:

Figure 1 is a side elevation of the improved apparatus; y ll Figure 2 is an end elevation of the apparatus shown in Figure 1; and

Figures 3 and 4 are detailed views showing the construction and arrangement of the float located in a compartment formed in the treating tank; and

Figure 5 is a detailed view. of the locking means. In lthe several drawings thenumeral 10 designates a'tank within'which the thread is to be treated by liquids used in washing or treating the thread in thel tank 10 of each LOCKING DEVICE Serial No. 562,592.

unit and conducted from separate storage tanks for these liquids through the filling lines 11a, 11b, and 110, etc., having branches 12a, 12?), and 12e, etc., with shut 0H valves 13a, 13b, 130, etc., said branches extending downwardly to provide outlets positioned on an are of a circle described about a point above the pivot 14.

A pipe 15 is supported by the frame 16 which may be nivoted about the pin 14. The upper end of the pipe 15 is provided with a sleeve 17 having a flared upper end and adapted to telescope within the pipe 15. A handle 18, as illustrated more clearly in Figure 5, is pivotally mounted at 19 on the support 20, which is clamped to the pipe 15. The inner bifurcated ends of the handle 1.8 provide arms 21, 21 carrying inwardly eX- tending pins uponwhich the rollers 21a, positioned between the flanges 22 and 23 fixed to the sleeve 17, rotate.

The lower end of the sleeve 17 carries a pin 24 about which the upper end of a rod 25 is bent to provide an elongated slot 26 Within which the pin 24 will slide when the sleeve is moved downwardly from its normal p0- sition. l/Vhen the sleeve 17 is raised the pin 24 will engage the hook at the top of the rod 25 to lift the rod. The rod 25 passes through the pipe 15 and is provided with a hook 27 at its lower end that engages an eye in the valve 28 extending into and covering the outlet 29 of the T fitting at the lower end of the pipe 15. A pin 18a, which may be passed through one of the three holes 185 in the support 20 and a hole in the handle 18 which registers with one of said holes in its raised, lowered and normal position, serves to retain the handle and the sleeve 17 in the desired position.

The horizontally extending outlet 30 o f the T fitting at the end of the pipe 15 communicates with the hole 31 in the bottom of the tank 10 through a pipe 32, a swivel connegtion positioned below the pivot 14, and a pipe 33. y

Drain lines 34a, 34?), etc., lead the liquids discharged from the tank 10 to separate tanks for the liquids to` be saved or reused or regenerated for reuse, and tothe sewer for liquids to be discarded. These drain lines are provided with receiving ports 35a, 355, 350, etc.,wl1ich are positioned directly beneath the outlet of the pipe 15 and the line 36 when the pipe 15 is connected to filling lines 11a, 11b, 11e, etc., respectively.

The tank 10 is provided with a vertical baille 37 extending across the tank from its top to within a short distance of its bottom. A horizontal baffle 38 is fixed to the baffle 37 nar its lower end and extends over the inlet 3 At one side of the end compartment formed by the baffle 37 an overflow pipe 39 is provided through which any excess of liquid in the tank 10 may be discharged. At the other .end of this end compartmenta float 40 is l positioned in a well 41 in the bottom of the tank 10. It is to be understood, however, that the use of a well is not necessary since the float may be positioned in the tank itself. However, this provision of a well is deemed preferable. A flexible cable 42 is fixed at one end to the float 40 and at its other end to a pin 43 so that a vertical movement of the float 40 will move the pin 43 horizontally through the .guide 43a, toward and from the sleeve 17. The length of the cable 42 is such that'when the float 40 is at its maximum height governed by the casing 44, the locking pin 43 will be advanced-toward the sleeve 17 a sufiicient distance to obstruct the downward movement of the sleeve 17. When the float 40 is in its lowest position the pin 43 will be withdrawn sufficiently to escape the fiange` 22 in order to permit the sleeve 17 to be lowered when the tank 10 and the well 41 are em ty.
